| Visico LE4421/LE4432 is a silane crosslinkable black compound system designed for insulation of low voltage energy cables and covering/insulation of overhead cables. Visico LE4421 is a low density polyethylene, copolymerized with vinyl silane. LE4432 is a crosslinking catalyst masterbatch specially designed to be used with Visico base resins. The system crosslinks quickly in sauna or in hot water. Cable insulation with a proper mixture of Visico LE4421 (90 parts) and LE4432 (10 parts) exhibits excellent thermo-oxidative stability. The combination is suitable for both copper and aluminum conductors. The final product contains nominal 2,5% of fine size carbon black ensuring excellent weatherability. Applications: Visico LE4421/LE4432 is designed for: Covering/insulation of overhead cables; Insulation of low voltage energy cables, range up to 6 kV Specifications: Visico LE4421/LE4432 in combination meets the applicable requirements as below when processed using sound extrusion and testing procedure: IEC 60502-1; ICEA S-105; Canadian Standards Association C22.2 No. 38 Cable Type RW-90 Outdoor; ANSI/ICEA S-70-547 Special Features: Visico LE4421/LE4432 insulation system offers: - Excellent processing properties
